Hi, I have seen a few blood sports on my pillow this morning (and a week ago as well) and I am worried about it. I have seen a doctor who though it could relate to reflux. So, I am taking medicine (a week now). Bu, it happens again. I have being have morning cough with a lot of sputum. I have also had X-Ray a month ago on my chest, and it was OK. So, please help me. Thanks. Li
